Need help with existing Powershell script

I've been working on a script that would allow us to search for multiple KBs against a list of remote servers. I managed to create a script that provides EXACTLY what I need, but I have yet to figure out how to get the script to accept multiple KBs as input as currently it only accepts one. I just need to someone to help me figure out how to get the script to accept multiple KBs as input, as the other 99% of the script is finished.

Looking to make some money?
